What is a Brake Lining?

What is a Brake Lining?

What is the brake Lining, what does it do, how often the brake lining is replaced, what should be done when the brake lining are gone, questions about the brake lining will be a content that contains information about the brake lining thanks to the main headings we have mentioned at the bottom.  When safety matters, the brake system comes first among the most effective mechanisms of a vehicle. Brake lining is one of the most important parts of the brake system. It is very important to carry out the maintenance of the brake lining periodically or to change the brake lining in terms of the duty undertaken by the brake lining.  

What is the Function of the Brake Lining?

What is a brake lining? What is the function of the brake lining? It would be more correct to explain the brake systems in advance without giving answers to such questions. Brake systems are a structure that transmits the force to the linings in the wheel system via the brake pedal in order to slow down the moving vehicles. If we need to make an explanation for the function of the Brake Lining, we can call the part that slows the vehicle down by friction against the brake disc or drum when force is applied to the brake pedal in this system.  When we carry out the replacement and maintenance of the Brake Lining at regular periodic times, the proper functioning of the brake pad means the life of the vehicle is extended.  

What does The Plate Of The Brake Lining?

The brake lining plate serves as the main foundation of the brake lining. The brake lining plate is responsible for the holding of the brake lining on the brake caliper and transferring its heat to other components in the Brake System.  Many brake linings have reverse side damping in the form of springs, foils, sheet steel and paint specially designed to minimize many disturbing noises generated during braking.  When the braking system is activated in the vehicle, that is, when the brake pedal is pressed and braked, the brake lining plate between the brake lining and the brake disc is pressed. There is a very thin adhesive layer only a few micrometers thick located between the brake lining plate and the substrate. This creates the safety boundary between the friction materials thanks to the plate and the intermediate layer.  

What to Consider in Brake Lining Selection?

Brake Lining should have values with high friction coefficients, this is to be able to preserve this friction coefficient in a wide range of heat values. As the temperature values in the brake pads increase, the friction coefficient decreases.

• Brake lining must be resistant to high temperature values.
• Brake lining materials must be resistant to abrasion for a long time. Brake lining should wear out gradually and brake lining should have a long service life, but at the same time they should not damage the brake lining.
• Brake lining should not make noise when rubbing. (Because these sounds cause extreme discomfort in the future)
• Brake lining should not lose their braking properties by glazing at high temperatures.
• Brake lining must be resistant to foreign substances such as dust, water and dirt.  

How Long Is The Life Of A Brake Lining?

There are many features that determine the life of the brake pad. The beginning of these is short;

• Brake lining models,
• The structure, softness or hardness of the brake lining,
• How you use the vehicle and how often you apply the brakes. 

The above mentioned items determine the lifetime of the brake lining. If we need to state the lifetime of the brake lining with an average, we can evaluate the life of the brake lining between 20.000 KM and 40.000 KM on average. Soft brake lining is one of the most common problems. Soft brake lining causes the lining to run out quickly. The hardness of the brake lining enables it to have a longer life. However, the disadvantage of hard brake lining is that it is more likely to make noise. If you press the brake very hard and drive your vehicle with a hard use, it is the cause of your brake lining to run out. On the contrary, a very soft use and slow pressing of the brake pedal will extend the life of the brake lining.  

How Do We Know That The Brake Lining Is Over?  

The easiest and simplest way to understand that the brake lining is finished is to apply force to the brake pedal, that is, when the brake pedal is pressed, there is noise from the brake, if the brake systems do not work as well as before. If it cannot brake suddenly in a short distance, the brake lining is over. Another way is that if the brake pedal has gone down to the lower levels, when you press the brake, it does not perform the full tightening process, in this case the brake pad is either worn out or finished. In this case, it is time to replace the brake pad.  

We can list the end of the brake pad in 3 items.  

• The sound of the brake when the brake pedal is pressed, 
• The brake lining is thinner than ¼,  
• The indicator lamp of the vehicle.  

Sound Of The Brake When The Brake Pedal Is Depressed? 

We explained above that the easiest way to run out of brake lining is the sound when the brake pedal is pressed. The main reason for this noise is the metal sheets placed on the brake lining. You will hear this sound every time the brake is pressed.  

Brake Pad is Thinner Than ¼ 

You have the chance to visually check the replacement time of the brake lining. If you can naturally look at the brake lining inside the rims and see that it is approximately 3 mm, we know that it is time to replace the brake lining.  

Vehicle Indicator Lamp 

Although rare, some vehicles have a warning warning lamp containing brake lining on their indicators. If you have this type of vehicle, you can tell from the warning lamp that the brake pad is finished.  

What Happens If The Brake Lining Is Run Out?

When the brake lining is finished, there remains a metal surface attached with the lining's riveting system. During each braking process, friction starts on the metal surface and the disc. This friction will cause great damage to the brake disc and make the brake disc unusable. Safety problems will occur as a result of the exhaustion of the brake lining, and at the same time, you will have financial damage. Because the end of the brake lining causes the braking system to drop by 80%. If the brake lining runs out, you should visit the nearest service at the lowest speed before exceeding a maximum speed of 30 km.  

How to Check Brake Lining?

If the brake lining is thinner than 3 mm or thinner than ¼ the above-mentioned brake calipers and at the same time creates scratches on the brake disc, we have checked that the brake pad is finished. Or, by pressing the brake pedal and listening to the sound made, we can check the brake lining.  

Brake Lining Thickness

The thickness of the lowest brake lining should be between 2-4 mm, but some brake lining models allow values such as 1.5 mm.
